Abstract: A flexible display apparatus including a substrate including a flat surface portion and at least one curved surface portion, and a display including a first display region above the flat surface portion and a second display region above the at least one curved surface portion. The second display region includes a correcting layer including a first point and a second point apart from each other. The second point is farther away from the first display region than the first point. A thickness of the correcting layer at the second point is greater than a thickness of the correcting layer at the first point. The correcting layer includes a curved portion between the first point and the second point.

Abstract: A display panel includes first pixels each including a first organic light emitting element which outputs red color light, second pixels each including a second organic light emitting element which outputs green color light, and third pixels each including a third organic light emitting element which outputs blue color light. The first organic light emitting elements are arranged in point symmetry with respect to the second organic light emitting element, the third organic light emitting elements are arranged in point symmetry with respect to the second organic light emitting element, an anode of the first organic light emitting element is spaced apart from an anode of the second organic light emitting element by a first distance, and the anode of the second organic light emitting element is spaced apart from an anode of the third organic light emitting element by a second distance which is shorter than the first distance.
